This invention relates to water pumping apparatus and particularly to one operatingbya wind-mill.

The main object of my invention is `to pro- 5 vide a windmill ot-this general character,

having,` a oldable vane and a brake mechanism tor halting the operation ot the windwheel, with asimple and positive means for vfolding the vane and applying the brake 10 whenever it is Ydesired to halt the operation ot the windmill. l

A further object of the invention is to pro. duce a simple and inexpensive ldevice and yet one which will be exceedingly eective l5 for the purpose for which it is designed'. These objects l accomplish by means of such structure vand relative arrangement ot parts as will fully appear by a perusal ot the following speciiication and claims. ln the drawings similar lnhai-acters of reference indicate corresponding parts in the several views: I

Refer-ring` now more `particularly to the characters of reference on the dra-wings, the numeral 1 denotes a. suitable vertical `trame which is surmounted by tubular member 2- .4.19 secured thereto. nTurnable on the tube is a sleeve 3 on the upper end of which is mounted a casing d, a. thrust bearing between the tube and sleeve permitting- 'free rotation of the latter and consequently of the casino. Projecting upwardly through the tube concentric therewith is the pump shaft 6 carrying the bevel pinion 7 on its upper end, the weight ot t-he shaft being talien by the pinion and by a thrust bearing` 8 between the pinion. and the top of the tube.

The pinion meshes with a. bevel gear 9 fixed on horizontal shaft 10, journaled in the casing, the outer end of the shaft having thereto.y

' By means Va wind wheel 11l or" common form .Secured of the labove arrangement it` will be seen that the casing and parts supported thereby are tree to rotate with any shift in the direction of the wind Without at* I "ecting,` the engaging of the gear and pinion as-wll be evident- F-voted oath@ @iid ,Of the easing opposite the wheel and normally projectingn outwa rdiyis a frame 12 which Supports a vertical wind vane 13, normally held in planeet right angles to the forward face ot tliewheel usual' by Mansion Sprlns 141- Tliis vonnis time .01* se as the following pulled to 21- motivierte-Ve PesitQ be parallel t0 the wheel by means.

connected thereto being prowith a full upward ymovement the upper end ot ythelever 21 forwardly or toward the' wheel 11 a distance suiiicienttocause the vane trame to be vswun laterally so that the vane is pary allel to the wheel.

.thefseparated collars 15 and 19 enables `lever whichcontrols the movement- @fileName-e be feed @e ai@ .teme Witheet interfering with the rotation of the collar 19 which would take place with any rotation of the casing.

At the same time as the vane is being thus moved to a non-operative position, the wind wheel is positively held from further rotation as follows: Fixed in connection with the shaft lO is a drum 23 about which a transversely split brake-band 24 is disposed, the band being anchored at one end to the casing 4 as shown at 25. The ends of the band are formed with radial ears 26 and a spring 27 between the ears normally holds the band clear of the drum. Turnable on the shaft l0 is an arm 28 one end of which carries a pin 29 to engageV the ear on the free end of the band and the other is connected to the collar 19 by a substantially vertical rod unit 30. The arm member is disposed so that when said collar is in its lowermost position the pin will be clear of the band ear but when the collar is raised said arm will be rotated to engage the ear and compress the spring sufficiently to cause the band to be frictionally contracted about the drum, thus of course holding the wind wheel from rotation. The rod unit may if desired be formed as a pair of telescoping members capable of a certain amount of loose play before moving together as shown. This would permit the collar to move up a certain distance before the band actuating arm functions, and allows of a shorter arc of movement of the arm than could otherwise be the case.

The pump shaft toward the ground projects through a casing 3l which is supported by the ground and extends to the .bottom of the well 32.

From the foregoing description it will be readily seen that I have produced such a device as substantially fulfills the objects of the invention as set forth herein.

IVhile this specification sets forth in detail the present and preferred construction of the device, still in practice such deviations from such detail may be resorted to as do not form a departure from the spirit of the invention, as defined by the appended claims.

Having thus described mv invention what I claim as new and useful and desire to secure by Letters Patent is:

l. A windmill including a supporting structure, a member turnably surmounted on the same, a horizontal shaft above and supported from said member, a wind-wheel on the shaft, a brake drum on the shaft, a band about the drum and anchored at one end, an ear projecting radially from the other end of the band, an arm rockably mounted on the shaft adjacent the drum, a pin projecting from the arm parallel to the shaft for detachable engagement with the ear, and means controlled from below the member for turning the arm to cause the pin to engage the ear and compress the band about the drum irrespective of the turning of said member relative to the supporting structure.

2. A Windmill including a supporting structure, a member turnably surmounted on the same, a horizontal shaft above and supported from said member, a wind-wheel on the shaft, a brake drum on the shaft, a band about the drum and anchored at one end, an ear projecting radially from the other end of the band, an arm rockably mounted on the shaft adjacent the drum, a pin projecting from the arm parallel to the shaft for detachable engagement with the ear, a sleeve slidable on the member, connecting means between the sleeve and the end of the arm opposite the ear to cause the arm to turn and the pin to be depressed against the ear when the sleeve is raised, and means for raising the sleeve at will.

3. A windmill including a supporting structure, a member turnably surmounted on the same, a horizontal shaft above and supported from said member, a wind-Wheel on the shaft, a brake drum on the shaft, a band about the drum and anchored at one end, an ear projecting radially from the other end of the band, an arm rockably mounted on the shaft adjacent the drum, a pin projecting from the arm parallel to the shaft for detachable engagement with the ear, a sleeve slidable on the member, means for raising the sleeve at will, and connecting means between the sleeve and arm arranged to turn the latter in a direction such that the pin will engage the ear only after a certain upward movement of the sleeve has taken place.

4. A Windmill including a supporting structure, a member turnably surmounted on the same, a horizontal shaft above and supported from said member, a wind-wheel on the shaft, a brake associated with the shaft,` lever means for applying the brake,.a vane swivelly mounted in connection with said supporting member for folding movement about a vertical axis, lever means for folding the vane, a sleeve slidable on the supporting member, means for raising the sleeve at will, a direct connection between the sleeve and the brake lever means to cause the brake to be applied When the sleeve is raised, and a separate and direct connection between said sleeve and `the vane lever means to cause the vane to be JOSE LECUONA.
